Front

What are supplementary angles?

Back

Angles that add up to 180°.

Front

What angle corresponds to angle 6?

Back

angle 2.

Front

Name the angle relationship when two parallel lines are cut by a transversal and the angles are on opposite sides of the transversal but inside the parallel lines.

Back

Alternate Interior.

Front

Name a pair of alternate interior angles when two parallel lines are cut by a transversal.

Back

angle 3 & angle 5.

Front

If angle 1 is 30°, what is the measure of angle 3 if angle 1 and angle 3 are corresponding angles?

Back

angle 3 = 30°.

Front

What are corresponding angles?

Back

Angles that are in the same position on two parallel lines cut by a transversal.

Front

If two parallel lines are cut by a transversal, what is the relationship between the alternate exterior angles?

Back

They are equal.

Front

What is the sum of the interior angles on the same side of the transversal when two parallel lines are cut by a transversal?

Back

180°.

Front

If angle 4 is 120°, what is the measure of angle 6 if angle 4 and angle 6 are alternate interior angles?

Back

angle 6 = 120°.

Front

What is the definition of vertical angles?

Back

Angles that are opposite each other when two lines intersect.
